Patent number: 9526894Abstract: A visual prosthesis and a method of operating a visual prosthesis are disclosed. Neural stimulation through electrodes is controlled by spatial maps, where a grouped or random association is established between the data points of the acquired data and the electrodes. In this way distortions from the foveal pit and wiring mistakes in the implant can be corrected. Moreover, broken electrodes can be bypassed and a resolution limit can be tested, together with testing the benefit the patient receives from correct spatial mapping.Type: GrantFiled: July 6, 2015Date of Patent: December 27, 2016Assignee: Second Sight Medical Products, Inc.Inventors: Robert Greenberg, Avraham Caspi, Jessy Dorn, Matthew J McMahon

Patent number: 8428739Abstract: This system gives the experimenter great flexibility to present spatio-temporal stimulation patterns to a subject. A video configuration file (VCF) editor allows the experimenter to determine the electrical stimulation parameters for each electrode. A Pattern Stimulation software program allows direct stimulation of chosen patterns of electrodes, scaled by the subject's VCF, through a Graphical User Interface. The subject then responds by drawing the outline of the phosphene he or she perceives on a touchscreen. The Pattern Stimulation program saves all of the trial parameters and the parameters of an ellipse fit to their drawing, as well as a raw data file containing the input to the touchscreen is saved. After the experiment, offline image analysis can be performed to obtain a detailed quantitative description of the subject's percepts. Image descriptors can assigned to the touchscreen data; these image descriptors can be used to make formalized comparisons between various experimental conditions.Type: GrantFiled: August 26, 2009Date of Patent: April 23, 2013Assignee: Second Sight Medical Products, Inc.Inventors: Ashish Ahuja, Avraham Caspi, Jessy Dorn, Robert J.

Patent number: 7957811Abstract: A visual prosthesis and a method of operating a visual prosthesis are disclosed. Neural stimulation through electrodes is controlled by spatial maps, where a grouped or random association is established between the pixels of the acquired image and the electrodes. In this way distortions from the foveal pit and wiring mistakes in the implant can be corrected. Moreover, broken electrodes can be bypassed and a resolution limit can be tested, together with testing the benefit the patient receives from correct spatial mapping.Type: GrantFiled: May 2, 2008Date of Patent: June 7, 2011Assignee: Second Sight Medical Products, Inc.Inventors: Avraham Caspi, Jessy Dorn, Matthew J.
